Serial No. 51,656, tiled by Frank S. Ingoldsby, March 18, 1901, and will not be herein more specifically described. When the lever h' is thrown to diseugage the doors, it operates on the inclined end of a bar h3 to disengage the raising-crank g2. This also has been fully set out in the prior patents.

We will now describe the central longitudinal truss, wherein our invention largely consists. The upper chord of this truss is a sheet-metal member B, in the form of an inverted V. This member may be made of one plate bent on its longitudinal medial line, as shown in most of the figures, or of two plates secured together by an outside angle b', riveted thereto, as shown in Fig. 13, or an inside angle b2, riveted thereto, as shown in Fig. 14. In any event it is one rigid member, and we shall speak of it as a plate irrespective of the number of pieces of which it is composed.

The plate B (which may be composed of as many longitudinal sheets as desired) is braced on its under side by members C C C2, riveted to it, and is thus enabled to itself constitute the upper chord or compression member of the truss. Of these members the braces C are of the form indicated in Fig. 7 and are employed at points where the toggle-raising members G are located. The members C' form both braces and struts and the members C2 simply braces. Each of these members carry door-hinges.

In the brace C, Fig. 7, there are two pairs of upright angle-bars c3 c3, riveted at their upper ends c4 to the plate B and at their lower ends to the malleable castings c5. These latter are braced by the angle cross-bar c6, riveted to each of them, and by the diagonal angle-bars cT c7, riveted to the castings and to the bars c3. A horizontal plate c8 extends across this brace between the two mem bers of each pair of uprights, being riveted to them. Outside of the members c3 are the malleable castings ci e9, riveted to each of these members. to the plate o8, and also to the top plate at cu.

In the struts C', Fig. 8, the vertical members may be made in one piece cl3, bent into U shape and at its lower ends secured to the malleable castings 015. The angle-braces c6 c7 c7 and plate c8 are the same as in Fig. 7. The malleable castings 019 stand outside of the vertical members clsand are riveted thereto and to the top plate.

In each of the malleable castings e9 and 019 there are formed holes 021 for the hinge-pintles of the door-beams h2. The casting ci has a bearing C22 for the toggleoperating shaft g, which is shown as tubular. The casting c5 has an eye o23 for the pin of the lower toggle member. The castings C15 carry bumpers e for the impngement of the floorbeams h2 and carry grooves c25 for the reception of tie-rods constituting the lower chord. It will be seen that these vertical struts and braces, being composed simply of plates, an-

gle-bars, malleable castings, and rivets, will be as light as is consistent with strength,while being cheap in construction.

At its ends the longitudinal plate B,const tuting the upper chord, is secured directly to the bolsters. The bolster is of the same general form as that shown in Patent No. 694,385 for a bolster granted to us March 4, 1902. It consists, briefly, of a center casting d, a channel-shaped compression member d', extending beneath the center casting and inclining upward on either side to the side of the car, and the tension-strap d2, passing over the top of the casting and inclining downward and riveted at its ends to the compression member through intermediate filling-blocks d3. Between the tension and compression members are vertical braces d4 and diagonal braces d5 and diagonal tension-rods d6, held together by the bolts C17. Diagonal I-beams J, extending from the sides of the car to the outer ends of the draftbeams,pass intermediately through the vertical braces d4 and are secured thereto. In the present invention, however, the bolster is made much higher at its center than shown in the prior patent referred to, and the top plate B extends directly across the center casting d, between it and the tension-strap d2, all three of these members being riveted together. The flanges at the upper side of the center casting d are inclined downward on each side, and the top plate B rests directly on these. Wedge-shaped lling-blocks da rest on the top plate, and the strap d2 passes over the filling-block and the top plate, and the same rivets dg secure all these parts together. The center casting preferably has cross-webs d and carries beneath the compression-channel a center bearing dm.

The draft-beam consists of two vertical plates E, extending across the bolster and riveted to the outer sides of the central frame thereof and engaging the under side of the plate B and riveted thereto, as at e. These draft-plates are .braced by suitable anglestrips e e2, riveted to their inner sides on the inner side ot' the bolster, and angle-strips e5 e3 e4, riveted to their outer sides beyond the bolster.

livers helping to sustain the central beam.

The flange of the center casting d of the bolster at its upper end extends toward the center of the car, as at dla, and there are riveted to this extension and to the top plate and draft-plates a pair of diagonal braces K, leading to the inclined ends P of the car, being secured to the angle-bar p, riveted crosswise of said end.

The lower chord of the longitudinal truss consists of a pair of U -shaped tie-rods L, passing at their bends over saddles N and secured at their ends by the turnbuckles M and occupying intermediately the bottom grooves 0250i the struts C'. The saddle N is grooved to receive the tie-rod and rests at its inner edge These draftplates being rigidly Y held at their outer portions act also as canta-Y ICO IIO

nal beam are all very effeztively hound together. At the same time the sides of the car are also rigidly bound through the bolster and the diagonal beams J, so that the tugging and bufng strains are efciently carried from one draft-beam to the other. The construction avoids the necessity of upper chordsin addition to the inclined upper plate,

which must be employed to shed the load, and the arrangement of longitudinal tie-rods with their turnbuckles allows adjustment, so that these tie-rods shall bear their proper proportion of the strain.

At the center of the car the sides are braced by the cross-plates R in an inverted-V shape. To prevent the sides near the middle of the car from bowing out at their upper ends, we provide a cross-tie. (Illustrated in Figs. 15, 16, and 17.) This consists of an angle-barQ, to each end of which is bolted an extension-bar q, as by the bolts q'.` This extension-bar has a threaded shank g2, adapted to extend through an openingin the side of the carand receive on its end a nut Q3.

When in place, the nuts g3 thus hold the car sides from bowing outward. The particular advantage of this construction is, rst, that it allows the parts to be very conveniently placed in the car, the extensions q be.

ing rst placed and then the bar Q bolted to them and then the nuts tightened up, and, second, it furnishesa very convenient method for drawing in the sides of the car if they should have become bowed out when the bar is not present. Thus the extensions q may have their shanks put through the openings in the bent car side and bolted to the bar Q and thereafter, the nuts g3 being tightened up, operate to force in the sides of the carto their proper position. A considerable displacement of the sides can be rectified in this manner. v
